Feed Conveyor feeds billets one-by-one to billet
lifter device & pusher. At the start conveyor
moves one full length, so that one billet is pushed
to a lifting tray on same level of roller. |
| The
Feed Conveyor is driven by Geared Motor with Chain
Sprocket Arrangement. The Conveyor Will forward
& Reverse facility (Electrically) is Provided
. Supporting structure is provided to accommodate
the feed rollers, drive unit for feed conveyor
and Billet guide to guide the Billet. |
| BILLET
HANDLING ROLLER CONVEYOR SYSTEM |
| The
cold billets are lifted one by one from ground
level of pallet/Tot box with Monorail Crane. Permanent
magnet lifter attached with hook of Monorail crane
and magnet lifter having UP and DOWN ,FORWARD
and REVERSE, ON /OFF hand lever operation. For
safety purpose of lever striker (locker) is provided.
When the permanent magnet on the billet surface
from the ground level, Turn the magnet lever to
ON position and lock the lever. Now the Billet
will be held by the magnet device. |
| - Normally
Billet is lifted from Ground “0” level to approximate
1.00 Mt.
|
| - The
Billet lifted with Magnet Device will move to
the centerline of the Conveyor and placed on the
damper tray of the feed Conveyor. |
| BILLET
EXTRACTOR WITH ACCEPT/REJECT DEVICE |
| The hot
billet comes out of the induction coil is received
by the billet extractor conveyor and stopped by
the stopper gate arrangements at the end of the
conveyor. The Stopper is operated by the hydraulic
Cylinder. |

|
The hot billet is sensed by (HMT) temperature
sensor. If the temperature is within the acceptable
range the stopper plate will open and the billet
is taken for next operation. |
| If the
temperature is not within acceptable range, the
billet is discarded with the help of Discarder
fingers placed in between rollers of extractor.
Discarder fingers are below the roller line while
normal operation to avoid any obstruction. Discarder
is operated by the hydraulic cylinder. |
| BILLET
LIFTER ASSEMBLY |
| When feed conveyor
moves, one full billet comes on this tray. The
Billet received from the feed conveyor to the
lifter. Then the Billet is lifted by the lifter
to the passing through induction Coil. Lifting
cylinder speed is controlled by flow control valve,
while return stroke is fast. Tray will orient
the billet at induction coil in flat face position.
Limit Switches are provided to control the stoke
length of cylinder. |

| BILLET PUSHER |
| The billet is aligned
along the coil, is pushed into the induction coil
by pusher mechanics fixed to the feed conveyor
structure. The Pusher mechanics consists of hydraulic
cylinders attached with the pushing ram guided
by rollers. The stroke of pusher is adjustable
for various sizes/ lengths of billets so that
on completion of one pushing stroke one full hot
billet comes out at the out feed end of induction
coil. |
| DAMPER
ASSEMBLY |
| A damper
tray having provision to move up/down 90mm vertically
with help of 4 nos of guide pushes & guide
rods provided at the start of rollers of feed
conveyor. At the beginning of process tray remain
up & billet is placed on tray in flat position.
Tray goes down after receiving the billet &
places it on roller feed conveyor in flat position.
The Tray up/down vertical motion controlled by
Hydraulic Cylinder. Limit switches provided for
indication the hydraulic cylinder motion. |
